Could we witness other universes begin?

    If the universe is a product of quantum fluctuations, isn't it possible then that we could witness new universes spring into existence around us?

    Independent of the unclear (!) origin of our universe, the universe is not something in space and time - it is space and time (with something inside). No, you won't see new universes popping up somewhere. You can see the effects of quantum fluctuations, however (Casimir effect, for example).
